* On Linux, the shm_open, sem_open, and related functions now expect the file shared memory file system to be mounted at /dev/shm Security related changes: CVE-2021-27645: The nameserver caching daemon (nscd), when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system CVE-2021-33574: The mq_notify function has a potential use-after-free issue when using a notification type of SIGEV_THREAD and a thread attribute with a non-default affinity mask CVE-2021-35942: The wordexp function may overflow the positional parameter number when processing the expansion resulting in a crash- nss-database-check-reload.patch, nss-load-chroot.patch, x86-isa-level.patch, nscd-netgroupcache.patch, nss-database-lookup.patch, select-modify-timeout.patch, nptl-db-libpthread-load-order.patch, rawmemchr-warning.patch, tst-cpu-features-amx.patch, mq-notify-use-after-free.patch: Removed- bsc#1181403- bsc#1184035- bsc#1187911- jsc#PED-987

* Tue Feb 02 2021 Andreas Schwab - Update to glibc 2.33
* The dynamic linker accepts the --list-tunables argument which prints all the supported tunables.
* The dynamic linker accepts the --argv0 argument and provides opportunity to change argv[0] string.
* The dynamic linker loads optimized implementations of shared objects from subdirectories under the glibc-hwcaps directory on the library search path if the system\'s capabilities meet the requirements for that subdirectory.
* The new --help option of the dynamic linker provides usage and information and library search path diagnostics.
* The mallinfo2 function is added to report statistics as per mallinfo, but with larger field widths to accurately report values that are larger than fit in an integer.
* Add to provide query macros for x86 CPU features.
* A new fortification level _FORTIFY_SOURCE=3 is available.
* The mallinfo function is marked deprecated.
* When dlopen is used in statically linked programs, alternative library implementations from HWCAP subdirectories are no longer loaded.
* The deprecated header and the function vtimes have been removed.
* On s390(x), the type float_t is now derived from the macro __FLT_EVAL_METHOD__ that is defined by the compiler, instead of being hardcoded to double.
* A future version of glibc will stop loading shared objects from the \"tls\" subdirectories on the library search path, the subdirectory that corresponds to the AT_PLATFORM system name, and also stop employing the legacy AT_HWCAP search mechanism.
* CVE-2021-3326: An assertion failure during conversion from the ISO-20220-JP-3 character set using the iconv function has been fixed.- Remove obsolete, unused /etc/default/nss- aarch64-static-pie.patch, euc-kr-overrun.patch, get-nprocs-cpu-online-parsing.patch, iconv-redundant-shift.patch, iconv-ucs4-loop-bounds.patch, ifunc-fma4.patch, intl-codeset-suffixes.patch, nscd-gc-cycle.patch, printf-long-double-non-normal.patch, strerrorname-np.patch, syslog-locking.patch, sysvipc.patch: Removed- bsc#1180557- bsc#1181505- bsc#1191592- bsc#1201942
